love failure

Tweet

i had been with friends who love. one of the studious guy loved a girl sincerely but she refused.then he became very dull in studies became addicted to bad habits. now his future is a question mark. i had an another friend who also failed in love but he was not dejected ,he became more and more positive,worked hard on studies and suceeded well in life. so my query is that love failure causes dejection or improvisation???
